No. vsasso,

van and State of'NeW York, have invented certain new and useful 'Improvements in I Iose, of the following is a specifica'- tion.-

' f The object of the invention is; to provide a i 'able' of other tube or hose which', While ca uses, shall be 'particularlyfa' apted for the control and passage ofsteam vor other Huid agent.-

Y Aiurther object is to so construct la hose designed for this vuse that the 'same shall erethrough. f

ferred form With these ends in view I construct the hose wholl'yof metal, this being in" ,the form of 'elongated strips, which, or cer- 'tain of which, may be previousl f'crimped or curved laterally to provide for t eproper co5I action oi all of such strips with another. These strips are formed into successive inter, locking spirals, the edges being in substantially parallel adjustment, but so arran ed relatively toeach other as toemit-readily flexing ior bending the hose Whi e in' use.' Thel h ose comprlses an inner series ofspirals,

formed, preferably, of copper, the adjacent edo'es thereof being secured together, refer-' abla in such'manner as to effect a sea The spirals of this series are provided with al circumferential ilange' o en'to the interiorof the series, the sides W ereo may `be readily moved toward for* from` each ojjher. The

spirals, preferably of steel,Y having angular edges terminating close tothe sidesof the clrcurnie'renti:il flanges of two adjacent spirals of the innerjseries. It further .comprises a second outer series of spirals, also 'referably of steel and substantial y AU-shape in'l crossf section, each ofthese coacting with the flange of oneof theinner series of s irals and withl the angular edge of each o two adjacent s ira'ls' ofthe irst outer series, thereby holding the'latt'er, as well as the sides of said flanges,

' as the hose 'is bent or curved. In a hose so constructed there is substantially'no deterioration due to the lflexing thereof in use. The tendency of the construction is to maintain the hose in a single plane. Upon over- V Patentdpc. 25, 1906.?

coming this tendency to bend the hose in any straightened out'.

' The invention is illustrated panying drawings, in Which- Fgll' 1. S a side elevation, partly in Specf tion,uol`- A4a hose constructed in accordance with my invention. Fig. 2 is an. enlarged section'of the construction shown in Fig.lv l.

These are-here shown as'formed'vrom a continuous strips of. metal, (preferably copper havingL some degree ofresiliency.) Such strip priorgroo'ved' or channeled is ormedint'o the sucV` to being formed intothe spirals shown is pro-v vided with a longitudinal groove or channel a of Isubstantial depth, the sides a a.l` thereof v extending'approximately at a right ang'leitov the portions a a'of thestrip-oneither'sde thereof. As' f a result when vthe stripfso t cessive spirals shown in Fig. 1 theexteriorcf# the series presents a circumferential and pref@v erably continuous flange,A the sides thereofbeibpg at rightr angles `to the longitude of` the tu e; .l

The acent edges ofeach two successive.l Ibo spirals A of the series are secured together 0 1' sealed in a suitable manner. Forl this purpose I have shown inf Figs. '1, 2 ,',3, and '4 'a sealingsstrip D, preferably of tinned cop er, overlyingt e butt-joint between the cent ed esof eachtwo successive spirals A.' Prefer'a ly tlie application of this sealing-strip n as described will follow immediately the form-v ing `of the spirals A A, said strip being erma'- f `nently secured in lace, as'lgthe so dering A process, as itis a` p ied. In s. 5 and 6 the adjacent'edges o veach two spirals are shown as secured together bymeans of a lap-andbeing curved into the -fold joint, and this may be made permanent by pressure alone or by the additional provision of solder, if desired.

B B designate the spirals of one of the outer series, Like the spirals A A', these are here shown as formed'from a continuous strip of metal, (preferably steel and prior to spirals shown the lateral edges of such str1 are flanged outward-ly at b b substantial Each of these spirals B B is of such width that on being .formed as shown in the drawings the external faces of the flanges b t shall bear against `or extend into proximity to the external faces. of ltwo adjacent spiral flanges aa, thereby aiding :in determining the degree of movement of such flanges toward each other. l

C C designate the spirals of the second outer series. Like the spirals A A and B B, these are here shown as formed from a continuous strip of metal, (preferably steel, and

I prior to being curved into the spirals shown such strip 1s provided with a groe ve or channel of substantial depth, which after the strip has been Wrap ed or bent to the conform-ation illustratedp presents an outwardlyextending flange c, corresponding generally in size and shape to, although a trifle larger than, the circumferential flange a, of the inner series of spirals A A. Said spirals C C are, as shown in the drawings, formed partly .upon said flange a and artly upon the outwardly-extending angu ar edges b b of the spirals B B. 'The preferred construction in this regard is that illustrated on enlarged scale in Fig. 2. Here, as will be seen, the sides c c and end c2 ofthe flange o closely encircle the sides a c and end a3 of the flange a. Near their edges the sides c c of each spiral C may be offset, (03,) so as to snugly receive between them and the sides-a a of the flange a the outturned-edges b of the two adjacent spirals B B.

The foregoing description ap lies generally to the construction shown in all)of the figures of the drawings. It is apparent, however, that the detail of such construction may be modi-fied to meet particular conditions without departing from the invention or sacrificing the advanta es inherent therein. Thus in Figs. 3 and 4 have shown a construction in which instead of employing a single strip for each of the series B and C of outer spirals, such strips bein of substantially the same thickness, I emp oy for one of the spirals (in this instance the spirals B) two parallel and preferably simultaneously-formed strips, each approximately one-half the thickness of the coacting spirals C.

Among the important adyantages which characterize the invention attention is called to the following: The hose made in accordance therewith possesses great strength and y at right angles to I `the intermediate portion.

would su ect the structure to undue strain,

is prevented by the sides c yc of the flange cl and in the particular embodiment of the invention here shown by the youtturned edges t b of the spirals B.. Again, the hose is absolutely steam and water tig-ht, the adjacent edges of the inner spirals being so securely sealed as toV make such spiralslin effect, ractically an integral structure. Added to t iis is the fact that the tendency of the 'fluidpressure within the hose is more in the direction of preserving the .integrity of the union between the spirals than in that of destroying it.
